试题的编制是教师的日常教学工作之一.笔者也一直在探索,如何迅速、高效地编制出合格的试题.在近期的学习过程中,笔者发现了下述的一个简单性质,现基于此性质,进行了几种试题的编题尝试.以此为例,与同行分享几种简单的命题方法.1.结论的发现指数函数f(x)=e~x的图像向右平移a(a>0)个单位,再向上平移b(b>0)个单位,可得函数g(x)=e~(x-a)+b的图像.那么这两个图像是否存在公切线呢? The preparation of test questions is one of the teachers’ daily teaching work. The author has also been exploring how to quickly and efficiently produce qualified test questions. In the recent learning process, the author discovered a simple property that is based on this nature. , for the trial questions of several test questions. As an example, share some simple proposition methods with the industry. 1. The findings of the conclusion that the exponential function f(x)=e~x shifts the image to the right a(a> 0) Units, then b(b>0) units upwards, get the image of function g(x)=e~(xa)+b. Then does the two images have common tangents?
